BIAWAK Quarterly Journal of Varanid Biology and Husbandry
BIAWAK Quarterly Journal of Varanid Biology and Husbandry Volume 4 Number 2 ISSN: 1936-296X On the Cover: Varanus obor Varanus obor is the most recent species of monitor lizard to be described from Indonesia. Discovered by Weijola and Sweet (2010. A new melanistic species of monitor [Reptilia: Squa- mata: Varanidae] from Sanana Island, Indone- sia. Zootaxa 2434: 17-32.), V. obor also repre- sents the most recently described member of the V. indicus complex. Data and observations on its natural history and ecology are included within the species description. The specimens depicted on the cover and inset of this issue were photographed by Valter Wei- jola on Sanana Island, Maluku, Indonesia on 28 March and 3 April 2009. The specimen depicted on the cover and to the left was observed around 1600 h in a coastal Sago area of northeastern Sanana. The specimen depicted below was first observed foraging in coastal vegetation, but as- cended a coconut palm when it noticed the ob- server.

Energetics and Biomechanics of Locomotion by Red Kangaroos (Macropus Rufus)
Comparative Biochemistry and Physiology Part B 120 (1998) 41–49 Review Energetics and biomechanics of locomotion by red kangaroos (Macropus rufus) Rodger Kram a,*, Terence J. Dawson b a Department of Integrati6e Biology, Uni6ersity of California, Berkeley CA 94720-3140, USA b School of Biological Sciences, Uni6ersity of New South Wales, Sydney NSW 2052, Australia Received 15 May 1997; received in revised form 22 September 1997; accepted 7 October 1997 Abstract As red kangaroos hop faster over level ground, their rate of oxygen consumption (indicating metabolic energy consumption) remains nearly the same. This phenomenon has been attributed to exceptional elastic energy storage and recovery via long compliant tendons in the legs. Alternatively, red kangaroos may have exceptionally efficient muscles. To estimate efficiency, we measured the metabolic cost of uphill hopping, where muscle fibers must perform mechanical work against gravity. We found that −1 uphill hopping was much more expensive than level hopping. The maximal rate of oxygen consumption measured (3 ml O2 kg s−1) exceeds all but a few vertebrate species. However, efficiency values were normal, 30%. At faster level hopping speeds the effective mechanical advantage of the extensor muscles of the ankle joint remained the same. Thus, kangaroos generate the same muscular force at all speeds but do so more rapidly at faster hopping speeds. This contradicts a recent hypothesis for what sets the cost of locomotion. The cost of transport (J kg−1 m−1) decreases at faster hopping speeds, yet red kangaroos prefer to use relatively slow speeds that avoid high levels of tendon stress. © 1998 Elsevier Science Inc. -

Post-Release Monitoring of Western Grey Kangaroos (Macropus Fuliginosus) Relocated from an Urban Development Site
animals Article Post-Release Monitoring of Western Grey Kangaroos (Macropus fuliginosus) Relocated from an Urban Development Site Mark Cowan 1,* , Mark Blythman 1, John Angus 1 and Lesley Gibson 2 1 Biodiversity and Conservation Science, Department of Biodiversity, Conservation and Attractions, Wildlife Research Centre, Woodvale, WA 6026, Australia; [email protected] (M.B.); [email protected] (J.A.) 2 Biodiversity and Conservation Science, Department of Biodiversity, Conservation and Attractions, Kensington, WA 6151, Australia; [email protected] * Correspondence: [email protected]; Tel.: +61-8-9405-5141 Received: 31 August 2020; Accepted: 5 October 2020; Published: 19 October 2020 Simple Summary: As a result of urban development, 122 western grey kangaroos (Macropus fuliginosus) were relocated from the outskirts of Perth, Western Australia, to a nearby forest. Tracking collars were fitted to 67 of the kangaroos to monitor survival rates and movement patterns over 12 months. Spotlighting and camera traps were used as a secondary monitoring technique particularly for those kangaroos without collars. The survival rate of kangaroos was poor, with an estimated 80% dying within the first month following relocation and only six collared kangaroos surviving for up to 12 months. This result implicates stress associated with the capture, handling, and transport of animals as the likely cause. The unexpected rapid rate of mortality emphasises the importance of minimising stress when undertaking animal relocations. Abstract: The expansion of urban areas and associated clearing of habitat can have severe consequences for native wildlife. One option for managing wildlife in these situations is to relocate them. -
Breeding Biology and Behaviour of the Scarlet

S.DEBUS Division of Zoology, University of New England, Armidale, New South Wales 2351 E-mail: [email protected] Received:I3 January 2006 The breeding biology and behaviour of the Scarlet Robin Petroica multicolor and Eastern Yellow Robin Eopsaltria australis were studied at lmbota Nature Reserve, on the New England Tableland of New South Wales,in 200G-2002by colour-bandingand nest-monitoring.Yellow Robins nested low in shelteredpositions, in plants with small stem diameters(mostly saplings,live trees and shrubs),whereas Scarlet Robins nested high in exposed positions, in plants with large stem diameters (mostly live trees, dead branches or dead trees).Yellow Robin clutch size was two or three eggs (mean 2.2; n = 19). Incubationand nestling periods were 15-17 days and 11-12 days respectively(n = 6) for the Yellow Robin, and 16-18 days (n = 3) and 16 days (n = 1) respectivelyfor the ScarletRobin. Both specieswere multi-brooded,although only YellowRobins successfully raised a second brood. The post-fledging dependence period lasted eight weeks for Yellow Robins, and six weeks for Scarlet Robins. The two robins appear to differ in their susceptibilityto nest predation, with corresponding differences in anti-predator strategies.

Exotic to Australia
Fact sheet Introductory statement Foot and mouth disease (FMD) is a highly contagious viral vesicular disease of cloven hoofed animals. It is a major issue in international trade in livestock and livestock products. Australia is free of the disease and it is vital that it remains so. The 2001 outbreak in the United Kingdom resulted in over 10 million cattle and sheep being slaughtered at a cost of over GBP 8 billion in order to eradicate the disease. This fact sheet summarises what is known about FMD and Australian native wildlife. WHA also manages an fact sheet that briefly summarises information on FMD and feral animals “Foot and Mouth Disease (General Information)”. Aetiology and natural hosts FMD is caused by an aphthovirus belonging to the family Picornaviridae. It is a single stranded non enveloped 25 nm RNA virus. There are seven serotypes: A, O, C, SAT 1, SAT 2, SAT 3, and Asia 1. All cloven hoofed animals are considered susceptible. Cases have also been reported in elephants, hedgehogs and some rodents. World distribution and occurrences in Australia FMD is endemic in Africa, the Middle East, Asia and parts of South America. The disease has almost been eradicated from Europe with the most recent cases occurring in the United Kingdom and Cyprus in 2007. FMD has not occurred in Australia for over 130 years, and then only in livestock. Minor outbreaks occurred in 1801, 1804, 1871 and 1872 (Geering et al 1995). However, a case was reported in an eastern grey kangaroo (Macropus giganteus) held in a zoo in India (Bhattacharya et al 2003). -

Eastern Grey Kangaroo Macropus Giganteus Shaw 1790 As a Vulnerable Species in Part 1 of Schedule 2 of the Act
NSW SCIENTIFIC COMMITTEE Preliminary Determination The Scientific Committee, established by the Threatened Species Conservation Act, has made a Preliminary Determination NOT to support a proposal to list the Eastern Grey Kangaroo Macropus giganteus Shaw 1790 as a Vulnerable species in Part 1 of Schedule 2 of the Act. Rejection of nominations is provided for by Part 2 of the Act. The Scientific Committee has found that: 1. Macropus giganteus Shaw 1790 (family Macropodidae), known as the Eastern Grey Kangaroo, is a large, highly sexually dimorphic macropod. Head-body to 2302 mm (males), 1857 mm (females); tail to 1090 mm (males), 842 mm (females); weight to 85 kg (males), 42 kg (females). Grey-brown dorsally, paler ventrally and on legs. Ears long, dark brown outside, pale grey inside with whitish fringe. Distal third of tail blackish. Muzzle finely haired (Menkhorst and Knight 2001; Johnson 2006; Coulson 2008). 2. Macropus giganteus is endemic to Australia. It is widely distributed in eastern Australia from Cape York Peninsula, Queensland, to far southeast South Australia and northeastern Tasmania. It is found throughout New South Wales (NSW). In western NSW, northwestern Victoria and southwestern Queensland M. giganteus is sympatric with its sister species the Western Grey Kangaroo (Macropus fuliginosus) (Johnson 2006; Coulson 2008). Eastern and Western Grey Kangaroos were recognised as separate species only in the 1970s (Kirsch and Poole 1972). Macropus giganteus mostly occurs where annual rainfall is >250 mm (Caughley et al. 1987b) in sclerophyll forest, woodland (including mallee), shrubland and heathland. It can also occur in modified habitats including farmland with remnant native vegetation, pine plantations and golf courses (Menkhorst and Knight 2001; Johnson 2006; Coulson 2008; Dawson 2012). -

Birdquest Australia (Western and Christmas
Chestnut-backed Button-quail in the north was a bonus, showing brilliantly for a long time – unheard of for this family (Andy Jensen) WESTERN AUSTRALIA 5/10 – 27 SEPTEMBER 2017 LEADER: ANDY JENSEN ASSISTANT: STUART PICKERING ! ! 1 BirdQuest Tour Report: Western Australia (including Christmas Island) 2017 www.birdquest-tours.com Western Shrike-tit was one of the many highlights in the southwest (Andy Jensen) Western Australia, if it were a country, would be the 10th largest in the world! The BirdQuest Western Australia (including Christmas Island) 2017 tour offered an unrivalled opportunity to cover a large portion of this area, as well as the offshore territory of Christmas Island (located closer to Indonesia than mainland Australia). Western Australia is a highly diverse region with a range of habitats. It has been shaped by the isolation caused by the surrounding deserts. This isolation has resulted in a richly diverse fauna, with a high degree of endemism. A must visit for any birder. This tour covered a wide range of the habitats Western Australia has to offer as is possible in three weeks, including the temperate Karri and Wandoo woodlands and mallee of the southwest, the coastal heathlands of the southcoast, dry scrub and extensive uncleared woodlands of the goldfields, coastal plains and mangroves around Broome, and the red-earth savannah habitats and tropical woodland of the Kimberley. The climate varied dramatically Conditions ranged from minus 1c in the Sterling Ranges where we were scraping ice off the windscreen, to nearly 40c in the Kimberley, where it was dust needing to be removed from the windscreen! We were fortunate with the weather – aside from a few minutes of drizzle as we staked out one of the skulkers in the Sterling Ranges, it remained dry the whole time.
